<div style="direction:ltr;font-family:Tahoma;color:#000000;font-size:10pt">Probably, you'd do it through an annotation layer. What version are you using? What interface (CGI, WMS, WCS)? Basically the idea would be to funnel the time parameter into a TEXT
expression in the annotation layer. Layer would look like (assuming a variable called 'time' is passed) this I think:
<div>
<div><br>
</div>
<div>LAYER</div>
<div> NAME 'timestamp'</div>
<div> TYPE ANNOTATION</div>
<div> STATUS DEFAULT</div>
<div> TRANSFORM LL # lower-left corner of the </div>
<div> FEATURE</div>
<div> POINTS 10 10 END</div>
<div> END </div>
<div> VALIDATION</div>
<div> 'time' 'some expression that matches time values'</div>
<div> END</div>
<div> CLASS</div>
<div> LABEL</div>
<div> ...</div>
<div> END</div>
<div> TEXT '%time%'</div>
<div> END</div>
<div>END</div>
<div><br>
</div>
<div>This would plop the passed time in the lower left corner of the output, or at least I think it should.</div>

Hi all,<br>
<br>
We have a set of time-series data. Is it popossible to add a time stamp, i.e. the value of time parameter in the request, on raster data? Thanks.<br>
